HONING-SUPPORT FOR SAFETY-RAZOR BLADES.

Specification of Letters Patent.

Patented July it, 1914.

Application filed May 8, 1913. Serial No. 766,264.

To all whom 2'1: may concern Be it known that I, FRED A. Nmnnn, a citizen of the United States of America, and resident of Augusta, county of Bracken, and State of Kentucky, have invented certain new and useful Ii'nprovements in Honingbupports for Safety-Razor Blades, of which the following is a specification.

This invention relates to honing supports for razor blades and particularly to sup ports for the. thin, afer-like blades which are. so generally employed with safety razors.

An object of the invention is to produce a simple, cheap and-eti'ective honing support for safety razor blades.

A further object is to produce a honing support in which means are employed for simplifying the operation of honing both cutting edges of a safety razor blade.

These and other objects I attain in a hon ing support embodying the features herein described and illustrated in the drawings accompanying and forming a part of this application.

In the drawings, Figure 1 is a perspective view of a honing support embodying my invention, and mounted on a hone. Fig. 2 is a sectional view of the honing support taken along the line 2-2 of Fig. 1. Fig. 3 is a sectional view of the support taken along the line 33 of Fig. 1.

The support illustrated as an embodiment of my invention comprises oppositely located wings or blade-engaging members 4 and 5, an intermediate hone-engaging member 6 and a pair of clamps T. which are mounted on the wing t and 5 and are employed for the purpose of forcing them into gripping engagement with a blade located between them. The wings 4 and 5 and the intermediate portion (3 are integrally formed, and are prcterably formed oi resilient n'i'aterial, such as spring steel or brass. The intermediate portion (3 is so arranged that it nor mally holds the wings 4 and 5 in such relative positions that they are spaced apart, about the thickness of a blade, with which they are to be employed. The member 4 is provided with :1 lug R, which is preferably struck from the metal 't'orming the wing and which projects toward the wing 5. The wing 5 is provided with an aperture t), into which the lug 8 is adapted to extend, when the wings are pressed into gripping en- 5 erably located midway between the ends of the wing & and is adapted to engage the central aperture of a safety razor blade, and to thereby lock the blade in place on the support. The length of the lug is such that it normally projects a slight distance beyond the inner edge of the aperture 9, so that it just intncepts the space between the wings -iand 5, when they are in their normal relative positions. The lug, however. is rounded, so that a razor blade can be readily moved between it and the wing 5, during the operation of mounting the blade on the support. lVith thi arrangement, the resiliency of the metal forming the wings, or of the metal formingthe intermediate portion (3, permits the wings to be sprung apart, when the blade is inserted between the lug and the wing 5, and then causes the lug to snap into place within the central aperture of the blade, when that aperture is moved into register with the aperture 9, in the wing The lug then holds the blade in place on the support, but permits it to turn freely about its central aperture.

A illustrated, the support is provided with two clamps 7, which are located at the ends of the support, so that the blade 10 is located between them, when it is in place between the wings 4 and Each clamp illustrated is U-shaped in form, and projects through apertures formed in the wings 4 and 5, and its legs are adapted to engage the outer surfaces of the opposed wings l and 5, and to press the wings into gripping engagement' with the mags. The wings are mcli-ned relatively to each other, so that they converge toward their outer or free ends, and the legs of each clamp also converge toward their outer or free ends and are so spaced that the clamps can be readily moved into engagement with the wings. When the clamps are turned so that their outer ends mo\e inwardly toward each other, or, in other words, toward the intermediate member (3, they force the outer edges of the wings l and 5 into gripping engagement with the blade 10, located between them. and the pressure between the wings and the blade increases as the ends of the clamps are moved closer to the intermediate memher. This is due to the fact that the wings are spaced 'farther apart at their junction with the intermediate member, and converge toward their free ends, as has been described.

The operation of mounting a blade on the support is as follows: The clamps 7 are both turned outwardly, so that their outer or free ends are moved off of or out of engagement with the wings; a blade 10 is then held so that it extends substantially at right angles to the length of the wings and one end is inserted between the wings and is forced past the lug 8, and between it and the wing 5. This moves the wings apart, so that the metal of the support is under strain. The blade is. then slipped to such a position that the lug snaps into its central aperture. This secures the blade to the support but does not prevent it from being turned relatively to the support. After the blade is secured to the support in the manner described, it is turned to such a position, with relation'to the wings, that one of its cutting edges extends parallel, or substantially parallel, to the outer or free edges of the wings. The clamps are then turned inwardly toward each other, so that their ends engage the wings and'in this way the blade is locked into position on the support and is firmly gripped by the Wings. The support is then placed upon the hone, so that its intermediate portion 6 and the pro- Jecting edge of the blade 10 engage the hone. The intermediate portion is preferably cylindrical, and of such diameter that when it is located in position on the hone it holds the blade'to be honed at a proper honing angle, with respect to the honing surface.

- In addition to this, the intermediate portion is bi-laterally symmetrical, with relation to the wings, and consequently, with relation to the blade located between them, and the supportcan therefore be so located on the hone that either side of the projecting edge of the blade can be presented to the honing surface. After one edge of the blade has been honed, the blade can be readily turned on the support, so as to present the other cutting edge, by merely loosening the clamps and turning it about the lug 8 and then moving the clamps again to the look-- ing position. This, is as apparent, is accomplished without removing the blade from the support and is a material advantage over other supports known to me.

The blade can be readily removed from the support by loosening the clamps, turning it so that it extends substantially at right angles to the length of the wings, and then withdrawing it from between the wings. The fact that the lug 8 is rounded, permits the blaoe to easily free itself therefrom-and the resiliency of the metal forming the support permits it to be withdrawn from between the end of the lug and the wing 5. During the withdrawing operation the honed edges of the blade are located between the free edges of the wings 4 and 5, and consequently, they do not come in contact with them. By turning the blade at right angles to the wings, as above described, the ln 8 does not come into contact with a hone edge of the blade, and consequently, does not damage the blade.

In accordance with the United States patent statutes, I have illustrated and described the preferred embodiment of my invention, but I desire it to be understood that various changes, modifications and substitutions may be made in the apparatus illustrated, without departing from the spirit and scope of my invention, as set forth by the appended claim. i

What I claim is:

A honing support for two edged blades, comprising two wings and an intermediate cylinder formed integral with the wings, the wings having a central pivot between them and so locatedrelatively to the cylinder as to permit rotation of the blade through one hundred and eighty degrees of a circle thereon, and clamps mounted on the wings upon opposite sides of the pivot, and adapted to be moved to positions which permit the rotation of the blade, or topositions which clamp the blade between the wings.

In testimony whereof, I have hereunto subscribed my name this 5th day of May,

FRED A. NEIDER. Witnesses: I
